Mobile App Development.
From a fast progressive web app to a polished cross-platform app in both stores: we help you choose the right route, then design, build, launch and support it.
What does mobile app development involve?
Mobile app development is the design, build and release of software for phones and tablets, together with the backend that powers it. The main routes are a progressive web app (PWA), a cross-platform app built once for iOS and Android, or separate native apps. Qodexify recommends the lightest option that meets your needs and builds it with design, APIs, testing and store release included. A cross-platform MVP typically takes 10–20 weeks and costs roughly $30,000–$90,000.
What’s included
What a mobile project includes
Product and UX design
Flows and prototypes designed for thumbs, small screens and real-world use, tested before development.
Cross-platform and native builds
React Native or Flutter for one codebase on both platforms, or native code where performance or device features demand it.
Backend and APIs
Accounts, data, notifications and integrations behind the app, built to scale with your users.
Device features
Camera, location, offline mode, push notifications, biometrics and payments where your app needs them.
Security and privacy
Secure sign-in, encrypted storage and careful handling of personal data and permissions.
Release and support
App store submission, beta testing, analytics, crash monitoring and ongoing updates for new OS versions.
Our approach
How a project runs
Discover and choose the route
We define the core job, your users and devices, and compare PWA, cross-platform and native.
Prototype
A clickable prototype is tested with real users before we build.
Build and beta test
We build in short cycles and test on real devices with a beta group.
Launch and improve
Store release, analytics and a plan for the first improvement cycles.
Use cases
Apps we build
Common projects where this delivers the fastest return.
Customer apps
Ordering, booking, loyalty and account apps that keep customers coming back.
Field service and operations apps
Job lists, forms, photos and signatures for teams on the move, including offline.
Companion apps for SaaS products
Mobile access to a web product, with notifications and quick actions.
Marketplace and booking apps
Two-sided apps with payments, chat and scheduling.
Internal business apps
Approvals, inventory and reporting on phones and tablets.
Progressive web apps
Installable web apps that avoid app store costs while you validate demand.
Cost & timeline
Typical timeline and budget
Indicative ranges for projects of this kind. Pricing depends on platforms, features, integrations and design complexity. Store fees and hosting are additional.
| Project type | Typical timeline | Typical budget |
|---|---|---|
| Progressive web app or mobile web app | 6–10 weeks | $20k–$45k |
| Cross-platform MVP (iOS and Android) | 10–20 weeks | $30k–$90k |
| Complex native or hardware-heavy app | 16–28 weeks | $80k–$180k |
FAQ
Frequently asked questions
Should we build a PWA, a cross-platform app or native apps?
Start with the lightest option that meets your needs. A PWA is cheapest, cross-platform suits most business apps and native is best for demanding performance or device features. Our mobile app options guide explains the trade-offs.
Do you build for both iOS and Android?
Yes. Most projects use one codebase for both, with native modules where needed.
Can you handle the app store submission?
Yes. We prepare listings, privacy declarations and builds, and manage review feedback.
What does it cost to maintain an app?
Plan for updates for new OS versions, bug fixes, backend hosting and store fees. We offer maintenance plans and can hand over to your team.
Will the app work offline?
It can. Offline support needs design from the start, so tell us how important it is in discovery.
Can you take over an existing app?
Yes. We begin with an audit of the code and architecture, then agree a plan to stabilise and extend it.
